We will deal with this in paragraph 6 when speaking about the means which God uses. Suffice it to give a few verses which point to this EFFECTUAL CALLING in Scripture. This is a special and EFFECTUAL CALLING subsequent to which people are justified. This is not the general call of the Gospel, but this is an effectual and indeed an Irresistible Call (see also chapter 10).
1Cor. 1:9 God is faithful, by whom you were called into the fellowship of his Son, Jesus Christ our Lord.
1Cor. 1:23-24 but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, 24 but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.
1Cor. 1:26-31 For consider your calling, brothers: not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth. 27 But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong; 28 God chose what is low and despised in the world, even things that are not, to bring to nothing things that are, 29 so that no human being might boast in the presence of God. 30 And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption, 31 so that, as it is written, “Let the one who boasts, boast in the Lord.”

Those whom He foreknew, were the same who were predestined, called and justified. Justification is by faith alone in Christ alone. Wayne Grudem says that:
Justification is an instantaneous legal act of God in which he (1) thinks of our sins as forgiven and Christ’s righteousness as belonging to us, and (2) declares us to be righteous in his sight.
Justification is best expressed in the third chapter of Romans.
Rom. 3:21-26 But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it—22 the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: 23 for all have sinned and fall short of the glory of God, 24 and are justified by his grace as a gift, through the redemption that is in Christ Jesus, 25 whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins. 26 It was to show his righteousness at the present time, so that he might be just and the justifier of the one ...
